Wedding open house?

Fiancé and I are eloping and wanting to just have an open house reception at our home since most have not met him yet or seen our home. I'll wear my dress and we'll decorate some having a video of wedding and pictures playing on tv etc. maybe a. Photo booth area

Any thoughts on food etc? Would drinks and dessert from 2-6pm on a Sunday be ok?

What would you expect at an "open house reception"? I know it's not traditional but I did the big church wedding and reception my first marriage
